Lemme see:
"Bleach adds bad chemicals to your water!"
"You need calcium in a your [vinyl-lined] pool."
"Total Alkalinity Raiser is 'different' than Arm&Hammer baking soda."
"You got a problem? You need clarifier, flocculent, pH Up, pH down, calcium, copper-based algaecide and 'Special' shock!"
"You lower T/A by pouring in a slug of Muriatic Acid. That crackpot aeration method is BS (barnyard slush)"
"A Nature2 will help keep your water clearer and reduce your chemical costs" (check out how much the yearly N2 cartridge costs--you can buy 2 season's worth of bleach for the same amount)
